IMPROVED SASH-HOLDER. I

The Schedule referred to in these Letters Patent and making part. of thesame.

To all whom it mag/*concern Bea knownmhat I, Dim R. Kum, of Alle.

town, in the county of Lehigh, and State of Pennsyl-V vania, haveinvented an Improved Sash-Lock; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanyingsheet of' drawings, and to the letters ofreferencemarked thereon. My invention consists of a sash-lock, in whichan eccentric or toe-cam, which projects downwardly from 1a slidinglever, a longitudinal slot of the lever, and a. recess or opening in thecase or frame of the window, areefnployed to retain the sash at anydegree of elevation or opening, and to lock it when down.

0n referenceto the accompanying sheet of drawings, making part of thisspecification- Figure 1 is a longitudinal section of a window-frame andsash,showing the sash when closed and locked, and also a supplementalview, showing the sash when raised Figure 2 is a sectional view of adetached part'of the windowlfm'me and sash, showing the position of ythelocking-lever when not engaged with the windowframe; `an d Figure 3 isan enlarged view of the locking-lever. Similar letters refer to similarparts Lin the several views. f

The locking-lever A is constructed with an eccentric or cam-foot B,projecting downwardlyfrom it. At-

the end adjacent to the casing or window-frame, at any convenient partoi' the body of it, a pin-slot, c, is formed 1engtl1wise,as shown. 'lThe outer end is turned upwardly, and forms the thumb-rest or handle j'.

An opening, D, is made through one side of the sash E, at any convenientpoint, the eccentric or camend of the lever A takes into it, and is heldfrom working out by a pin, d, on which it slides and vibrates.

When the window is down, andV it is required to raise and support it atany particular poin-t, the

thumb-end f, of' the lever,.must be elevated, to clear the eccentricfrom the frame crease, as shown in iig. 2. When it is at the designatedpoint, as shown in the supplemental view, fig. 1, the thumb-end must beor foot to engage against the oppois generated to pre gravity. Theeccenthe.` frame, and, by forcing the sash site side of it," sufficientAfriction vent it from falling, by its own tric or cam holds tighter andmore firmly, the greater the downward pressure on the sash.

The sash, when down o r closed, is locked, so-as not to be raised fromwithout, as follows:

An opening or mortise, g, is formed in the 'frame F,- corresponding, inposition, with the lever A. When the sash is at its lowest point, thelever is tilted, as shown in Iig. 2, and shoved forward, by reason ofthe pin-slot c, into the recess or mortise g, the top of that end of thelever engages with the top of the mortise,

and the top of the body of the lever bears against the top of theopening D, of the sash. The pin d, in the slot e contributes anupwardly-bearing pressure. In this casel the eccentric or cam does nocome into play.

It will be seen, from iig. 1, and its supplemental View, and iig. 2,that the top ofthe opening D, ofthe sash E, is bevelled upwardly,outwardly and inwardly. The outwardly-inclined bevel is to assist thelock in holding the sash open or raised, as shown iu the supplementalview'of iig. 1, by giving .it an inclined bearing, thereby permittingthe swell of the cam to more fully contact or press against the frame orcasing of the window. The inwardly-inclined bevel assists the lock inholding the sash down or closed, as shown in g. 1. 4

The lever A has two downwardly-bearing pressures, viz, the top of theopening in the casing oi" the window, and the inwardly-inclined bevel ofthe opening D, of the sash, and one upwardly-bearing, viz, the pin d.

I am aware that a earn or eccentric has been heretofore used forsash-locks, and is therefore not the subject of a patent,` in itself,being an old device. I

am also aware that a cam, moving on a pin, in a slot, is notnew. f

What I claim as my invention, and desire to secure by Letters Patent,is-

The lever A, with its cam or `eccentric B, and slot c, in combinationwith the piud, the opening D of I the sash, with its double incliies orbevels, and the mortise g, in the case or farne of the window,suhstantially as shown and described.

In testimony whereof, I hereunto sign my name. to' this specification,in\preseuce .of two subscribing-wit nesses.
